UIC Box Bogie
1. Brief Description :
-
UIC Box Bogie is a Bogie which is used in BOX, BCX, BCXT, BRH, BRS type wagons.
The BOX bogie is designed for an axle load of 20.3 tonne. It is an all welded, plate fabricated
bogie having a fixed bolster with hemispherical centre pivot and primary suspension
incorporating four laminated bearing springs with long links supported by mild steel
stones. The suspension arrangement and axle box design with liberal lateral and
longitudinal clearance are intended to permit the wheel set to "float" relative to the
bogie frame, with the object of improving the riding characteristics of the bogie.
The roller bearing axle boxes are provided with "L" type lugs, so that in its lateral
movement, wheel set is constrained by only one axle box at a time and there is no
reversal in bending of bogie sole plate.
